	Using libavformat and libavcodec
		I describe the changes to the libavformat / libavcodec API in this article.
		The libavformat and libavcodec libraries that come with ffmpeg are a great way of accessing a large variety of video file formats.
		Our job is to read these packets one by one using libavformat, filter out all those that aren't part of the video stream we're interested in, and hand them on to libavcodec for decoding.

	Facts about topic: (FFmpeg) (Site not responding. Last check: )
		It includes libavcodec, a leading audio/video codec library.
		libavcodec is a library (A depository built to contain books and other materials for reading and study) containing all the ffmpeg audio/video encoders and decoders.
		Most codecs were developed from scratch to ensure best performances and high code reusability.

	Doom9's Forum - mencoder command for libavcodec und xvid
		The documentation of mplayer/mencoder is a little bit outdated, too, but i have found a draft for a up to date "Making a high quality MPEG4 ("DivX") rip of a DVD movie" page.
		I want to use this as a startpoint for libavcodec encoding, and ask you what to change/improve to get a good quality two CD-R rip of a movie from DVD, or anime content capured with a analog capture card which adds lots of noise.
		Libavcodec seems to be much better in doing the hard to compress movies.

	FFmpeg Documentation (Site not responding. Last check: )
		libavcodec is the library containing the codecs (both encoding and decoding).
		You can use libavcodec or libavformat in your commercial program, but any patch you make must be published.
		fprintf and printf are forbidden in libavformat and libavcodec, please use av_log() instead.

	ffmpeg denial of service - Mandriva - Xatrix Security
		Simon Kilvington discovered a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS and potentially to compromise a user's system.
		The vulnerability is caused due to a boundary error in the "avcodec_default_get_buffer()" function of "utils.c" in libavcodec.
		This can be exploited to cause a heap-based buffer overflow when a specially-crafted 1x1 ".png" file containing a palette is read.

		It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.
		Only problem is that MPEG-2 playback can't play the SVCD clips directly from the CD, but requires the video to be extracted to the HDD by using VCDGear first.

	COWON America Forums - View Single Post - Can I make a suggestion for future JetAudio enhancements?
		Set libavcodec as the decoder in a format so ffdshow runs when a file of that format is opened.
		If you want to use it DVDs or VCDs, you should set MPEG1 and 2 to libavcodec.
		But consider that those formats aren't fully implemented in ffdshow, so may may see artifacts or a performance decrease.

	libavcodec tests
		The choosen scene includes (maybe 10s) a view of continuously projected water and rain, something libavcodec doesn't like very much.
		This format was also choosed to speed a bit the tests : mencoder doesn't have to decompress / crop / scale before sending the frames to libavcodec.
		PSNR : peak signal to noise ratio, as given by the ve_lavc.c module from mplayer / mencoder.

	FFmpeg
		Thanks to dedicated multimedia hackers from the FFmpeg and x264 projects, FFmpeg's libavcodec can already decode the next-generation (buzzword alert!) H.264 video codec data inside the latest Apple QuickTime files.
		Along with the free, open source FAAD AAC decoding library (for the audio track) and a competent QuickTime file demuxer, open source software is already equipped to handle the newest multimedia files on the internet.
		It includes libavcodec, the leading audio/video codec library.

	Philips 642 and MEncoder/ffmpeg/libavcodec - Topic Powered by Groupee Community (Site not responding. Last check: )
		libavcodec is know to make mpeg2 that's "too much vbr" for dvd-players, but mpeg4 is inherently vbr so it shouldn't be that(it shouldn't bve, but it may be..heh) it may also be interleaving; as dvp said, check with gspot.
		I can't argue that MEncoder's libavcodec can beat latest and greatest versions of DivX and XVID in terms of video quality.
		But, subjectively, I couldn't see any drastic differences in quality between libavc, DivX, XVID when I use their default settings.

	[No title]
		The actual CVS version of libavcodec has divx5 abilities, so you might want to get it when using other versions: cvs \ -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg\ login && [press enter for password] cvs -z3 \ -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg\ co ffmpeg/libavcodec && cd ffmpeg &&./configure --prefix=
		/libavcodec Now ffmpegs libavcodec will be available for mplayer.
		Since the docs are pretty good, only a short example of a three-pass libavcodec divx5 encoding of a dvd: rm frameno.avi mencoder -dvd 1 -aid 128 -ovc frameno -oac mp3lame \ -lameopts vbr=3 -o frameno.avi # mencoder should output bitrates for average encodings # now, choose one of your liking!

	Codecs - MPlayer - The Movie Player for Linux
		If you have a Win32 codec not listed here which is not supported yet, please read the codec importing HOWTO and help us add support for it.
		If you use MPlayer from CVS you have to extract libavcodec from the FFmpeg CVS tree as FFmpeg releases don't work with MPlayer.
		Actually there are two (nearly equal) decoders for SVQ1: one is built in MPlayer, the other is in libavcodec.

	Transcode_Wiki: Building Transcode
		Transcode comes with a library for AVI files, avilib, and a library for decoding ac3 audio, libac3.
		You will need to have libavcodec (also known as ffmpeg libraries) installed somewhere on your computer.
		The best way to accomplish this is to get ffmpeg from cvs (www.ffmpeg.org), configure it with at least --enable-shared, compile and install it.

	Just the usual rant: Debian VS legal problems (MPlayer, xine, libavcodec)
		Take a look at libxine1.deb : xineplug_decode_ff.so 829032 - this is libavcodec, the MPEG4/DivX decoder Did you pay the royalty to the MPEG Group?
		xineplug_decode_faad.so 164048 - this is the FAAD audio decoder, which is just as illegal as libavcodec Vidix - unusable ballast without libdha, which is not packaged nvidia_vid.so - part of Vidix..
		ASF demuxer - Microsoft already forced a GPL project to remove it (VirtualDub) I hope Debian is also ready to face this :) xineplug_decode_gsm610.so - xine's gsm610 is GPL, MPlayer's is not?

	DivX vs libavcodec
		Again, the author meant the MPEG-4 codec from libavcodec.
		This is a common confusion - DivX is not a format, it's a commercial MPEG-4 codec made by DivX Networks.
		There are other MPEG-4 codecs, some of them open-source (libavcodec, XviD).
